We added a new feature in gladlyCast (for both Singapore and Malaysia) during our previous maintenance.
We noticed a few users trying to direct message their friends and Twitter just wouldn't deliver these messages out. From now on, it will be handled correctly as a direct message. To send a direct message use:
d username messageFor example:d gladlycast When are you going to support DM via SMS?This would send a direct message "When are you going to support DM via SMS?" to us if we (gladlyCast) are following you.
Note that while you can send a DM to your friend on Twitter, you cannot receive a DM with your phone.
If you're still unsure about how direct message works in Twitter, take a look at this helpful article from Twitter.
